.To all whom it may concern: I i

Be it known that I, BERNHARD WAGNER, merchant, a subject of the King of Prussia, residing at` N o. 26 Mauerstrasse, Berlin, German Empire, have invented new and useful Improvements in Apparatus for Coking Briquets, of which the following is a specification. i

In the manufacture of so-ealled patent or brick fuel, otherwise known as Ubriquets,"with the aid of acementing or binding agent which is soluble in water attempts have already been made to rend er the blocks or briquets weather roof by coking the binding medium. Suc i experiments, however, in many respects have not proved satisfactory. In the rst place it has not been possible to heat a large number of briquets simultaneously in such manner that each individual brick is exposed to the furnaces-gases `uniformly on all sides, but without burning-that is to say, so that all the artsmay be submitted uniformly to the coiiing process. There have been, moreover, no devices whereby the process can proceedin regular uninterrupted manner and the coking -chamber and furnace-gases be thoroughly utilized.

According to my invention the furnacegases pass through a continuous tubular casing, and the briquets also are `caused to travel along it in such manner that all parts-of each briquet are subjected to a uniform coking process without there being any danger of the briquet burning or being disturbed or injured. For this purpose the briquets are conducted through the coking-casing in continuous succession, one butting against the other, so as to form, as it were, a long train or rope. The rate of advance should be suflici ently slow to admit of the binding agent being thoroughly coked when the respective briquet again leaves the casing.

My invention is illustrated in the accompanying drawings, in which-- ratus.

Figure 1 is a longitudinal section, and Fig. 2 a cross-section, of oneform of the new appa- Fig. 3 is a cross-section of a modification of the same, in which three adjacent col(- ing-chambers are shown. Fig. 4 is an elevation and part longitudinal section of an apparatus having an inclined rotary easing. Fig. 5 is a cross-section of the same. Fig. 6 illustrates the successive positions occupied by the briquets during rotation of the casing shown in Figs. 4 and 5. Figs. 7, 8, arid t) are three cross-sectional views illustrating various methods of dividing the coking-casing into a plurality of chambers. Fig. 10 is a longitudinal section of an apparatus inwhich the coking-casing is' divided into a large number of chambers. Fig. 11 is a cross-section through Fig. 10. Fig. 12 is a longitudinal section illustrating a complete plant embody ing the coking apparatus shown in Figs. l() and 11.

1 is a sheet-metal casing into which the furnace-gases enter at 2, passing thence along the casing and making their exit at 3. The briquets the binding agent of which is to be coked are introduced at 4--for instance, with the aid of a wing or blade 5, which in rotating seizes the pressed briquet on the feed-board (i and advances it toward the mouth 1 of the .casing 1. Each time a new briquet comes before the wing 5, which is in constant rotation,` the briquet is advanced through a certain distance, (for example, through the length of a briquet,) so that it strikes against the briquet whicli is already lying in the mouth 4, (for instance, on a wirewori tray or sieve -7,) whereby the briquets in passing through the casing form, as it were, a continuous train or rope of blocks. At the end of the sieve 7, which supports the briquets, is the exit'lO of the casing 1, which exit is normally closed by a flap 11, which is only opened (if desired, automatically) when a sufficient number of briquets have collected in the chute 10, so that the latter may discharge itself, the briquets thus being delivered onto a traveling band 12. The purpose of the flap 11, which ordinarily closes the chute 10, is to prevent as far as possible the entry of fresh air into the eoking-chamberethat is to say, to prevent burning of the briquets.

As Fig. 1 shows, each briquet must travel through the entire length of the casing 1, and since each briquet is always fed uniformly into the easing it is obvious that every briquet will remain therein for the same length of time. It will further be observed from Fig. 1 that the furnace-gases pass in the opposite direction tothe line of briquets. ln this manner the briquets fed into the easing will first encounter the relativelyv le'ast hot, furnace-gases, while the farther they are advanced into the easing in the direction of the exit 10 the hotter tbe gases which they meet. This` method prevents the briquets at the connnencement of the coking process from being suddenly subjected to the hottest fur- IOO IOS

vss

nace-gases, whereby, also, -they would be burned or cracked on their entry into the coking-chamber.

Instead of a single casing 1 a plurality of such might be employed, as is illustrated in Fig. 3, where three such casiugs are located side by side, each casing being traversed by the furnace-gases and fed with briquctsin the manner described. In thisway 'several trains 0i briquets, each of which `-may consist of several rows, are subjected simultaneously tothe coking process, whereby at the exit of each individual casing weatherproof briquets are delivered.

Instead of the briquets being heated uniformlyV all round by being deposited on a sieve the briquets may bc placed directly upon the wall of the casing 1 and during their passage through the latter be regularly turned over, so that all the faces of the briquet, one after the other, are subjected to the action of the furnace-gases. Such an arrangement is illustrated in Figs. 4-'and 5. The casing 1 is here somewhat inclined and rotated with the aid, for instance, of supporting-rollers 13 and driving-gear 14. The briquets fed into the 'casing from the feed-board 1'5 arc then by reason ofthe inclined position and the rotary motion of the casing slowly advanccdand at the same time turned over,

as shown in Fig. 6.

With this apparatus in the same way as 'described with reference to Figs. 1 to 3 several trains of' briquets may be subjected to the coking operation simultaneously, as it is only necessary to select a casing of greater yposition of the casing each individual group of briquets will be continuously advanced and at the saine-time turned over for the purpose of enabling the furnace-gases to act on `every side. Since the feed of briquets tothe inlet of the casing goes on continuously and uniformly and since likewise the briquets are regularly distributed into the several compartments of the casing, the Working proceeds uninterruptedly in the most advantageous manner possible, the entire cokingchamber and the whole of the furnace-gases being'utilized to the greatest advantage.'

Figs. 10 and 11 show in longitudinal" and cross-section, respectively, an apparatus especially adapted for the wholesale manufacture of briquets, in which the latter are turned and fed forward automatically-` yThe casing 1 is here subdivided into a large number of chambers or compartments, each of which is destined to receive a supply of briquets, which during the slow rotation of the v6r, casing pass through a chute' or feed-channel 16 into the mouths of those chambers located 'for the time being before the chute and then travel through the coking-chambers until they reach the delivery end of the casing.

Fig. 12 showsa complete plant iii-which thel coking apparatus illustrated in Figs. 1() and 11 is incorporated. 17 is a furnace from which the gases pass to\ the' casing 1 and thence through the various compartments or chambers to the smoke-chamber 18, 'from which they may be drawn off by means of a suitable exhauster or the like. The briquets travel in the opposite direction to the iurnace-gases and on the periodical lopening of the flap 11 are delivered through the chute 10 onto a traveling band 12. The arrangement of a smoke-chamber 18 prevents air which enters through -the ,chute 16 from obtaining access to the interior ofthe coking-chambers, as on leaving the exit of the chute`16 (be-v tween its mouth'and the end of the drum 1) the air immediately makes its way to the flues. Similar provision `is made also in the apparatus shown in Figs. 1 to 4, where the air entering at 4 is immediately conducted to, the outside by the flue-pipe 3, so that it does not enter the actual coking-chamber.
